Solarcentury’s C21e solar plain tile system delivers universal compatibility with small format plain tiles and an excellent performance per m², providing a perfect complement to a traditional plain tiled roof.

**No extra planning:** The C21e solar plain tile system sits flush with standard roof tiles, to provide a traditional finish. They protect your home from the elements whilst producing electricity.

**Ease of installation:** Fitted to standard wooden battens using traditional roofing practice, with one C21e covering the width of approximately seven conventional tiles.

**No specialist skills:** Designed to be installed by roofers, as part of the roof build, the C21e solar plain tile system fits ‘straight out of the box’ without the need for bespoke flashings or fillers.

**Fast to fit:** As fast to fit as traditional plain tiles, and complete with simple click-to-fit connectors, allowing all of the electrical work to be carried out within the building. Dimensions
